Ugh... my half-sister reeks of double standards.
In the time that I was with her, she complained that I'm using up too much electricity whenever I'm not at work or doing something useful. What does she do at her home?? She sits on the living room couch & either watches prerecorded shows that are on her DVR, or plays games on her tablet, all while leaving her daughter mostly unattended.
If that's not bad enough, she goes into a fit whenever anyone besides her talks about buying something - it has to be for her intentions only, or else she's keeping the money for herself.
To sum it all up, my tolerance for these such people is zero. I try my best to set up a good example of what a person is going to be, & if someone is going to mooch off of me, they're going to fall way out of favor with me.
